    La red teórica de la dinámica de poblaciones.Martín Díaz & Pablo Lorenzano - 2018 - Scientiae Studia 15 (2):307.
    The general aim of this article is to carry out a reconstruction of the theory of Population Dynamics (DP) in Ecology, according to Castle’s (2001) general stance with regard to the semantic view of theories, but doing it within the framework of metatheoretical structuralism. Thus, we will first identify Population Dynamics’ basic theory-element: its core K(DP) – with the class of potential models, the class of models (through the identification of its fundamental law) and the class of partial potential models (...)

    21世纪的自杀性乌托邦妄想: 哲学,人性与文明的崩溃.Michael Richard Starks - 2020 - Las Vegas, NV USA: Reality Press.
    美国和世界正处于人口过度增长的崩溃过程中,大部分都发生在上个世纪,现在这一切都是由于第三世界人民造成的。资源消耗和增加10亿至2100亿美元,将使工业文明崩溃,并造成饥饿、疾病、暴力和战争。" ;数十亿人将死去,核战争几乎可以肯定。在美国,大规模移民和移民再生产,加上民主带来的滥用,大大加速了这一速度。堕落的人性无情地把民主和多样性的梦想变成犯罪和贫穷的噩梦。崩溃的根本原因是我们天生的心理无 法适应现代世界,这导致人们把不相关的人当作他们有共同的兴趣对待。再加上对基本生物学和心理的无知,导致部分受教育者的社会工程妄想,他们控制着民主社会。很少有人明白,如果你帮助一个人,你伤害了别人——没有 免费的午餐,任何人消费的每一件物品都会破坏地球,无法修复。因此,世界各地的社会政策都是不可持续的,如果不严格控制自私,所有社会都会陷入无政府状态或独裁。如果不立即作出戏剧性改变,就没有希望阻止美国或任 何遵循民主制度的国家的崩溃。因此,我的文章"民主自杀"。 现在很清楚,统治中国的七个社会道路正在赢得第三次世界大战,所以我关于他们的结论性文章。唯一更大的威胁是人工智能,我简要地评论。 我们一切的关键是生物学,而正是它所忽视它,导致数百万聪明受过教育的人,如奥巴马,乔姆斯基,克林顿,民主党和教皇支持自杀的乌托邦理想,无情地直接导致地球上的地狱。 正如W指出的,我们眼前最难看的就是什么。 我们生活在有意识的议事语言系统2的世界里,但它是无意识的,自动反射系统1的规则。这是西尔的《现象幻象》(TPI)、平克的《空白石板》和《图比》和《科斯米德的标准社会科学模型》中描述的普遍失明的根源。 第一组文章试图让我们了解我们是如何合理摆脱理论错觉的。在接下来的三个组中,我评论了阻碍可持续世界的三个主要错觉——技术、宗教和政治(合作团体)。人们相信社会可以由他们拯救,所以我在书的其余部分提供一些 建议,为什么这不太可能通过短篇文章和评论最近出版的著名作家的书。 另一节描述了宗教错觉——有一些超级力量会拯救我们。 下一节将数字错觉描述为将系统2的语言游戏与系统1的自动化混为一谈,因此无法区分生物机器(即人)和其他种类的机器(即计算机)。 其他数字错觉是,我们将从系统1的纯邪恶(自私)由计算机/AI/机器人/纳米技术/基因工程由系统2创建。 没有免费午餐校长告诉我们,将有严重,甚至致命的后果。 最后一节描述了"一个幸福家庭"的幻想,即我们被选中与大家合作,如果我们只是正确管理事情(政治的可能性),民主、多样性和平等等异想天意将引导我们进入乌托邦。 再次,没有免费午餐原则应该警告我们,它不能是真实的,我们看到整个历史和整个当代世界,没有严格的控制,自私和愚蠢占上风,并很快摧毁任何国家,拥抱这些妄想。此外,猴子的头脑大大折扣的未来,所以我们合作出售 我们的后代的遗产为临时舒适,大大加剧了问题。 .

    The Economics, Ethics, and Ecology of Companion Animal Overpopulation and a Mathematical Model for Evaluation the Effectiveness of Policy Alternatives.Joshua Mayer Frank - 2001 - Dissertation, Rensselaer Polytechnic Institute
    This dissertation focuses on the effectiveness of various methods of reducing the cost of unwanted dogs. A mixed ecological-economic model of animal flow dynamics is utilized to study the impact of various treatments on dog overpopulation. It is found that utilizing such a model which includes long-term and indirect effects can have a large impact in the estimated effectiveness of treatments. Survey results for the New York State Capital Region are utilized to estimate model parameters, analyze the effectiveness of policy (...)

    If you consult a medical textbook to learn about the pathogenesis of Lyme disease, you will find a standard narrative. You will learn the disease is caused by the spirochete Borrelia burgdorferi, which is transmitted to people by blacklegged ticks . You will also learn that the natural reservoir for spirochetes in the Northeast is the white-footed mouse , and also likely be told that white-tailed deer are the primary host for gravid female ticks.

    I present an attempt at an explication of the ecological theory of interspecific competition, including its explanatory role in community ecology and evolutionary biology. The account given is based on the idea that law-like statements play an important role in scientific theories of this kind. I suggest that the principle of competitive exclusion is such a law, and that it is evolutionarily invariant. The principle's empirical status is defended and implications for the ongoing debates on the existence of biological laws (...)

    Trade-Offs in Model-Building: A More Target-Oriented Approach.John Matthewson - 2011 - Studies in History and Philosophy of Science Part A 42 (2):324-333.
    In his 1966 paper “The Strategy of model-building in Population Biology”, Richard Levins argues that no single model in population biology can be maximally realistic, precise and general at the same time. This is because these desirable model properties trade-off against one another. Recently, philosophers have developed Levins’ claims, arguing that trade-offs between these desiderata are generated by practical limitations on scientists, or due to formal aspects of models and how they represent the world. However this project is not complete. (...)

    In this paper, we present a deterministic time discrete mathematical model based on multiregional periodic matrices to describe the dynamics of Sardina pilchardus in the Central Atlantic area of the Moroccan coast. This model deals with two stages and three spatial zones where sardines are supposed to migrate from one zone to another. The population dynamics is described by an autonomous recurrence equation N = A.N, where A is a positive matrix whose entries are estimated using data collected during biannual (...)

    Economics and social sciences in general have a long tradition of using theories, models, concepts, and so forth borrowed from the natural sciences to describe and explain the properties and behaviours of economic and social entities. However, unwarranted application of theoretical elements from the natural sciences in the economic/social domain can have adverse consequences for organisations, their employees and society in general. Focusing on biology and organisation studies, we discuss the general problems that may arise when theoretical elements from natural (...)

    Approach for Qualitative Validation Using Aggregated Data for a Stochastic Simulation Model of the Spread of the Bovine Viral-Diarrhoea Virus in a Dairy Cattle Herd.Henri Seegers, Chantal Guihenneuc-Jouyaux, Christine Jacob, Christine Fourichon & Anne-France Viet - 2006 - Acta Biotheoretica 54 (3):207-217.
    Qualitative validation consists in showing that a model is able to mimic available observed data. In population level biological models, the available data frequently represent a group status, such as pool testing, rather than the individual statuses. They are aggregated. Our objective was to explore an approach for qualitative validation of a model with aggregated data and to apply it to validate a stochastic model simulating the bovine viral-diarrhoea virus (BVDV) spread within a dairy cattle herd. Repeated measures of the (...)

    Types of Experiments and Causal Process Tracing: What Happened on the Kaibab Plateau in the 1920s.Roberta L. Millstein - 2019 - Studies in History and Philosophy of Science Part A 78:98-104.
    In a well-cited book chapter, ecologist Jared Diamond characterizes three main types of experiment performed in community ecology: laboratory experiment, field experiment, and natural experiment. Diamond argues that each form of experiment has strengths and weaknesses, with respect to, for example, realism or the ability to follow a causal trajectory. But does Diamond’s typology exhaust the available kinds of cause-finding practices? Some social scientists have characterized something they call “causal process tracing.” Is this a fourth type of experiment or something (...)

    America and the world are in the process of collapse from excessive population growth, most of it for the last century, and now all of it, due to 3rd world people. Consumption of resources and the addition of 4 billion more ca. 2100 will collapse industrial civilization and bring about starvation, disease, violence and war on a staggering scale.

    Analysing Population Numbers of the House Sparrow in the Netherlands With a Matrix Model and Suggestions for Conservation Measures.Chris Klok, Remko Holtkamp, Rob Apeldoorn, Marcel E. Visser & Lia Hemerik - 2006 - Acta Biotheoretica 54 (3):161-178.
    The House Sparrow (Passer domesticus), formerly a common bird species, has shown a rapid decline in Western Europe over recent decades. In The Netherlands, its decline is apparent from 1990 onwards. Many causes for this decline have been suggested that all decrease the vital rates, i.e. survival and reproduction, but their actual impact remains unknown. Although the House Sparrow has been dominant in The Netherlands, data on life history characteristics for this bird species are scarce: data on reproduction are non-existent, (...)

    Of all global problems world population growth is the most significant. The growth of the number of people expresses the sum outcome of all economic, social and cultural activities that comprise human history. Demographic data in a concise and quantitative way describe this process in the past and present. By applying the concepts of nonlinear dynamics and synergetics, it is possible to work out a mathematical model for a phenomenological description of the global demographic process and project its trends into (...)

    Informative Ecological Models Without Ecological Forces.Justin Donhauser - 2020 - Synthese 197 (6):2721-2743.
    Sagoff (2016) criticizes widely used “theoretical” methods in ecology; arguing that those methods employ models that rely on problematic metaphysical assumptions and are therefore uninformative and useless for practical decision-making. In this paper, I show that Sagoff misconstrues how such model-based methods work in practice, that the main threads of his argument are problematic, and that his substantive conclusions are consequently unfounded. Along the way, I illuminate several ways the model-based inferential methods he criticizes can be, and have been, usefully (...)

    Towards an Ecological View of Immunity. [REVIEW]Swiatczak Bartlomiej - forthcoming - Studies in History and Philosophy of Science Part A.
    The immune system does not just fight pathogens but also engages in interactions with beneficial microbes and non-immune cells of the body to harmonize their behavior by means of cytokines, antibodies and effector cells (Dinarello, 2007; Moticka, 2015, pp. 217e226, 261e267). However, the importance of these “housekeeping” functions has not been fully appreciated (Cohen, 2000). In his new book Immunity: The Evolution of an Idea Alfred I.

    An Extensionist Environmental Ethic.Gary Comstock - 1995 - Biodiversity and Conservation 4 (8):827-837.
    Environmental ethics consists of a set of competing theories about whether human actions and attitudes to nature are morally right or wrong. Ecocentrists are holists whose theory locates the primary site of value in biological communities or ecosystems and who tend to regard actions interfering with the progress of an ecosystem toward its mature equilibrium state as prima facie wrong. I suggest that this form of ecocentrism may be built on a questionable scientific foundation, organismic ecology, and that a better (...)

    Biological Conservation of a Prey–Predator System Incorporating Constant Prey Refuge Through Provision of Alternative Food to Predators: A Theoretical Study.Kunal Chakraborty & Sankha Subhra Das - 2014 - Acta Biotheoretica 62 (2):183-205.
    We describe a prey–predator system incorporating constant prey refuge through provision of alternative food to predators. The proposed model deals with a problem of non-selective harvesting of a prey–predator system in which both the prey and the predator species obey logistic law of growth. The long-run sustainability of an exploited system is discussed through provision of alternative food to predators. We have analyzed the variability of the system in presence of constant prey refuge and examined the stabilizing effect on predator–prey (...)

    Outcomes of interspecific competition, and especially the possibility of coexistence, have been extensively studied in theoretical ecology because of their implications in community assemblages. During the last decades, the influence of different time scales through the local/regional dynamics of animal communities has received an increasing attention. Nevertheless, different time scales involved in interspecific competition can result form other processes than spatial dynamics. Here, we envision and analyze a new theoretical framework that couples a game theory approach for competition with a (...)

    Mathematical modeling is a convenient way for characterization of complex ecosystems. This approach was applied to study the dynamics of zooplankton in Lake Sevan at different stages of anthropogenic eutrophication with the use of a novel method called discrete modeling of dynamical systems with feedback . Simulation demonstrated that the application of this method helps in characterization of inter- and intra-component relationships in a natural ecosystem. This method describes all possible pairwise inter-component relationships like “plus–plus,” “minus–minus,” “plus–minus,” “plus–zero,” “minus–zero,” and (...)

    A simple numerical procedure is presented for the problem of estimating the parameters of models for the distribution of eggs oviposited in a host. The modelling is extended to incorporate both host density and time dependence to produce a remarkably parsimonious structure with only seven parameters to describe a data set of over 3,000 observations. This is further refined using a mixed model to accommodate several large outliers. Both models show that the level of superparasitism declines with increasing host density, (...)

    Explaining the persistence of populations is an important quest in ecology, and is a modern manifestation of the balance of nature metaphor. Increasingly, however, ecologists see populations (and ecological systems generally) as not being in equilibrium or balance. The portrayal of ecological systems as “non-equilibrium” is seen as a strong alternative to deterministic or equilibrium ecology, but this approach fails to provide much theoretical or practical guidance, and warrants formalisation at a more fundamental level. This is available in adaptation theory, (...)

    Evaluating the Models and Behaviour of 3D Intelligent Virtual Animals in a Predator-Prey Relationship. AAMAS 2012: 79-86.Deborah Richards, Jacobson Michael, Taylor Charlotte, Taylor Meredith, Porte John, Newstead Anne & Hanna Nader - 2012 - Proceedings of the Eleventh International Conference on Agent and Multiagent Systems (AAMAS).
    This paper presents the intelligent virtual animals that inhabit Omosa, a virtual learning environment to help secondary school students learn how to conduct scientific inquiry and gain concepts from biology. Omosa supports multiple agents, including animals, plants, and human hunters, which live in groups of varying sizes and in a predator-prey relationship with other agent types (species). In this paper we present our generic agent architecture and the algorithms that drive all animals. We concentrate on two of our animals to (...)

    Demography and Diffusion in Epidemics: Malaria and Black Death Spread.J. Gaudart, M. Ghassani, J. Mintsa, M. Rachdi, J. Waku & J. Demongeot - 2010 - Acta Biotheoretica 58 (2-3):277-305.
    The classical models of epidemics dynamics by Ross and McKendrick have to be revisited in order to incorporate elements coming from the demography (fecundity, mortality and migration) both of host and vector populations and from the diffusion and mutation of infectious agents. The classical approach is indeed dealing with populations supposed to be constant during the epidemic wave, but the presently observed pandemics show duration of their spread during years imposing to take into account the host and vector population changes (...)

    Neutral Theory, Biased World.William Bausman - 2016 - Dissertation, University of Minnesota
    The ecologist today finds scarce ground safe from controversy. Decisions must be made about what combination of data, goals, methods, and theories offers them the foundations and tools they need to construct and defend their research. When push comes to shove, ecologists often turn to philosophy to justify why it is their approach that is scientific. Karl Popper’s image of science as bold conjectures and heroic refutations is routinely enlisted to justify testing hypotheses over merely confirming them. One of the (...)

    Fisheries Management and Complex Dynamics.Barkley Rosser - manuscript
    Fishery dynamics are considered within the context of an integrated ecologiceconomic, or bioeconomic, approach. The possibility of complex dynamics is examined, both of the chaotic as well as the catastrophic variety. Issues involving learning and convergence by fishers are considered. Complications arising from multi-species interactions are considered as are complications arising from the hierarchical nature of fisheries. Policy responses to these problems are seen to involve the precautionary..

    Discrete Conventional Signalling of a Continuous Variable.Magnus Enquist, Stefano Ghirlanda & Pete L. Hurd - forthcoming - Philosophical Explorations.
    In aggressive interactions, animals often use a discrete set of signals, while the properties being signalled are likely to be continuous, for example fighting ability or value of victory. Here we investigate a particular model of fighting which allows for conventional signalling of subjective resource value to occur. The result shows that neither perfect nor no signalling are evolutionarily stable strategies in the model. Instead, we find ESSs in which partial information is communicated, with discrete displays signalling a range of (...)

    A Learning Strategy for Predator Preying on Edible and Inedible Prey.A. Tsoularis - 2007 - Acta Biotheoretica 55 (3):283-295.
    In this paper I propose a reinforcement learning model for a predator preying upon two types of prey, the unpalatable (noxious) models, and the palatable mimics. The latter type of prey resembles the models in appearance so as to derive some protection from the predator who must avoid the unpalatable models. Essentially the predator is treated as a learning automaton adopting a simple reinforcement learning strategy in order to increase its consumption of palatable prey and reduce the consumption of unpalatable (...)
